This calculus video tutorial explains how to identify points of discontinuity or to prove a function is continuous / discontinuous at a point by using the 3 step continuity test. This involves evaluating piecewise functions using one sided limits. The first step is to determine if the function is defined at the given point. The second step is to prove that the limit exists by showing that the right side equals the left side. If the limit does not exist, it could be a jump discontinuity or an infinite discontinuity which are nonremovable. The 3rd step is to show that the limit equals the function at the given point. If the limit exists but does not equal the function, then it's a point discontinuity also known as a hole which is removable.

Tim Brzezinski shows Alice Keeler how easy it is to teach math with GeoGebra. This is the first part of a 3 part series. The format for this is exactly what the title says, Tim is teaching Alice. So Alice is asking a lot of questions and is directing Tim to help her with what she wants to know. This is not Alice hosting Tim for a webinar. It is intentionally structured this way. Tim does a LOT of Geogebra webinars and trainings, check out his many other ways to learn more about Geogebra. For follow up join the Facebook group https://www.facebook.com/groups/geogebraeng/ where Tim is an active member.

In which John Green teaches you about railroads and some of the ways they changed the world, and how they were a sort of microcosm for the Industrial Revolution as a whole. Prior to the invention of steam-powered railroads, pretty much all locomotion had been muscle-powered. You either walked where you wanted to go or rode on an animal to get where you were going. The railroad changed human perception of time and space, making long-distance travel much faster and easier. Railroads also changed habits, including increasing reading. People needed some sort of distraction to ensure they didn't have to talk to other people on the train. Like any new technology, railroads also scared people. All kinds of fears surrounded rail travel, but over time, people got over them. And the quality of boiler manufacturing improved, so the trains exploded less often, which also made people feel safer.

Geometry on Khan Academy: We are surrounded by space. And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large--from math to architecture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine ("It's good for you!"), it's at the core of everything that exists--including you. Having said all that, some of the specific topics we'll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That's a lot. To summarize: it's difficult to imagine any area of math that is more widely used than geometry.

Algebra II on Khan Academy: Your studies in algebra 1 have built a solid foundation from which you can explore linear equations, inequalities, and functions. In algebra 2 we build upon that foundation and not only extend our knowledge of algebra 1, but slowly become capable of tackling the BIG questions of the universe. We'll again touch on systems of equations, inequalities, and functions...but we'll also address exponential and logarithmic functions, logarithms, imaginary and complex numbers, conic sections, and matrices. Don't let these big words intimidate you. We're on this journey with you!

X-linked inheritance involves traits found on the x chromosome.
Humans have 23 pairs of chromosomes. Females inherit two x chromosomes and males inherit an x and y chromosome.
The x chromosome has many more genes than the y chromosome. As a result, you get what is called an x-link trait.
In this video, I show a Punnet square of an x-link chromosome and why males may inherit the trait more often than females.
